I've noticed a couple times recently that whenever I hit the accelerator between 1/4 and 1/2 throttle to merge on to the interstate that my car will develop a really really nasty knock/rattle/tick. Whenever I hear that I let off the gas a bit and it goes away. I will say that down here in TX, the only gas I can get is 92 or 91 octane instead of my normal 93 (unless some one in the Wichita Falls, TX area knows of a station that has 93 octane ). Is this due to the lower octane gas or is it something more serious?
The only "mod" I have is a drop in K&N and a gutted airbox. BTW, it definitely improved that spool sound/BPV sound when I did that
